Here is a litle system I have been playing around with using common sense rules

1. Must have place S/R of 60% or higher
2. Must have win S/R of 15% or higher
3. Must not be resuming from a spell
4. All horses in the race must have run at least 4 career runs.
5. Must be only 1 selection in the race.

It came out of a place system I found somewhere and it looked like some commonsense rules. In particular I liked how it was aiming to target the most conistent runner in the race (60% placings).

Anyone able to test this system ? or any thoughts ?

I haven't done any testing so for all I know it may have poor results.
